Rangers lefty Jake Diekman underwent successful surgery to remove his colon, with several more procedures to come as he battles ulcerative colitis. Evan Grant of the Dallas Morning News has the latest, including video diary entries from Diekman himself. It’s well worth a watch to learn more about the unfortunate affliction and Diekman’s fight. We hope to see him back on the mound as soon as possible.

There won’t be a return in the offing for Phillies lefty Matt Imhof, who lost his eye in a terrible accident involving exercise bands. As Imhof himself writes in a moving piece for ESPN.com, he’s returning to finish his degree at Cal Poly San Luis Obispo and will retire from the sport. He says it’s not just due to the injury, though; as he writes, “the truth is I need a change of pace after 20 years of doing the same thing.” You’ll want to give a full read to the southpaw’s powerful story of coming to grips with — and not being defined by — his injury.

As we wish the best to Diekman and Imhof, here’s the latest on the market for pitching:

As the Mets look to bolster their bullpen, the team is still weighing a variety of free agents, per Ken Rosenthal of FOX Sports (via Twitter). In addition to keeping open the possibility of a reunion with lefty Jerry Blevins, the Mets are also considering righties Sergio Romo and Joe Smith.

The Reds are exploring a reunion with former starter Bronson Arroyo, as Buster Olney of ESPN.com reports (Twitterlinks). Unsurprisingly, the team is not interested in guaranteeing him a roster spot, as Arroyo is two full years removed from appearing in the majors and has dealt with significant arm issues of late. GM Dick Williams confirms that the team has watched Arroyo throw and is weighing a signing, per MLB.com’s Mark Sheldon (Twitterlinks). Beyond a move on Arroyo or other candidates for minor-league deals, Cincinnati is done with its free-agent signings, Williams adds.

Speaking of longstanding veterans weighing returns, righty Jason Marquis suggested in an appearance on MLB Network Radio on Sirius XM (Twitter link) that he’s open to reviving his career. The 38-year-old last appeared in a nine-start stint with Cincy in 2015, but he’s set to pitch for Team Israel in the upcoming World Baseball Classic.

While Dodgers lefty Julio Urias showed plenty in 2016 to warrant a rotation spot in the coming season, innings considerations may hold him back to start the year. As Andy McCullough of the Los Angeles Times tweets, skipper Dave Roberts says that the organization may keep him in extended Spring Training at the beginning of the 2017 campaign. Such an approach would not only ensure that Urias is available for good once he does make it up, but would afford more opportunities for the organization to see what it has in its variety of interesting, injury-plagued arms. Over at Fangraphs, Craig Edwards takes a look at what’s shaping up to be a fascinating staff.

There’s an argument to be made that the Nationals not only need to address their closer situation, but also ought to bolster their rotation depth, as Chelsea Janes of the Washington Post writes. While the team’s five-man starting unit is likely set, which perhaps limits their ability to promise opportunities to free agents, a swingman could make sense. Janes mentions Travis Wood as at least a hypothetical match, and he would indeed seem to make a sensible fit.

31-year-old Cardinals reliever Mitch Harris is hoping to join former teammate Seth Maness in bouncing back from a “primary repair” procedure to his right elbow, as Derrick Goold of the St. Louis Post-Dispatch reports. Harris last pitched competitively in 2015, but will be ramping up for a full spring after undergoing the surgery last summer. Because his surgeon was able to attempt that less-invasive approach, as opposed to a full UCL replacement, there’s a possibility of a much swifter return to the hill — though Harris will first need to earn his way into MLB camp after failing to receive an invite.

Marquis, 36, posted a 6.46 ERA in 47 1/3 innings with the Reds across nine starts. Though his 7.0 K/9 rate and 2.7 BB/9 rate are both markedly better than his career numbers in those categories, Marquis was very homer-prone. He’s also seen his typically excellent ground-ball rate dip back to about the league average, so the increase in the percentage of fly-balls against him that leave the yard has been magnified by the fact that he’s giving up fly-balls at a higher rate in previous years.

The veteran Marquis won a spot in Cincinnati’s rotation this spring when Tony Cingrani was shifted to the bullpen. While Cingrani has taken well to pitching in relief, Marquis has did not experience that same level of success in the rotation.

Marquis, a client of ACES, spent much of the 2014 campaign recovering from Tommy John surgery. He ultimately signed a minor league deal with the Phillies, but he also worked out in front of Reds scouts. He circled back to Cincinnati when he signed with the Reds in January, but his stay did not last through the summer.

For his career, Marquis owns a 4.61 ERA with 5.4 K/9 and 3.5 BB/9 over the course of 15 seasons.

The Reds announced that they have designated right-hander Jason Marquis for assignment today (Twitter link). The move paves the way for the team to select the contract of right-hander Jon Moscot, who will start tonight’s game versus the Padres. Additionally, Cincinnati has placed righty Raisel Iglesias on the disabled list with an oblique strain and recalled right-handed reliever Pedro Villarreal from Triple-A Louisville in his place.

The veteran Marquis won a spot in Cincinnati’s rotation this spring when Tony Cingrani was somewhat unexpectedly shifted to the bullpen. While Cingrani has been one of the team’s more effective relievers in terms of ERA, Marquis has not experienced success in the rotation.

Marquis, 36, has totaled a 6.46 ERA in 47 1/3 innings with the Reds across nine starts. Though his 7.0 K/9 rate and 2.7 BB/9 rate are both markedly better than his career numbers in those categories, Marquis has been very homer-prone. He’s also seen his typically excellent ground-ball rate dip back to about the league average, so the increase in the percentage of fly-balls against him that leave the yard has been magnified by the fact that he’s giving up fly-balls at a higher rate in previous years.

The 23-year-old Moscot entered the season ranked 20th among Cincinnati farmhands by both Baseball America and Fangraphs, while MLB.com was a bit more optimistic, ranking him 14th. The consensus among the three scouting reports is that Moscot has a fifth starter’s ceiling thanks to four average pitches. BA notes that he lacks a true plus pitch, and while he has better pure stuff than former Reds farmhand Ben Lively (who was traded to the Phillies in exchange for Marlon Byrd), Lively misses far more bats due to better deception on the mound. FG’s Kiley McDaniel notes that while fifth starter is the upside, the Reds should be pleased if he turns out as a middle reliever or long man as well.

Reds catcher Devin Mesoraco did not travel with the team and instead remained in Cincinnati to undergo an MRI on his hip, tweets John Fay of the Cincinnati Enquirer. Catcher Kyle Skipworth will fill in for the time being, as he’s had his contract selected from Triple-A, the Reds announced. (A corresponding 40-man move will happen prior to tonight’s game.) The Reds entered the season with quite a few injury question marks, but Mesoraco was not thought to be one. Clearly, losing Mesoraco for any significant amount of time would be crushing for a Cincinnati team that many have already picked to struggle in the NL Central, though it’s too early to tell exactly how great the level of concern surrounding Mesoraco should be.

A few more notes from baseball’s Central divisions…

Fangraphs’ Craig Edwards breaks downRaisel Iglesias’ debut against the Cardinals yesterday, noting that while the start didn’t alleviate concerns about Iglesias’ ability to work deep into games, he showed enough to suggest that he can get big league hitters out on a consistent basis, even if it ultimately has to come in a relief role. With Homer Bailey nearing a return from the DL, the Reds will have to make a decision between Iglesias and veteran righty Jason Marquis. For the time being, that’s been solved by optioning Iglesias to Louisville, but Edwards wonders if it’d be a better decision to eventually let Iglesias develop at the highest level — a move that would seemingly force Marquis into the bullpen or off the Cincinnati roster.

Bill Brink of the Pittsburgh Post-Gazette spoke toPirates GM Neal Huntington about the decision to pursue a long-term contract with Josh Harrison. “When you believe in the person and you believe in the abilities of that person, and it aligns with where you want to go, you’re able to find the common ground, it makes all the sense in the world,” Huntington told Brink. As Brink points out, not all deals of this nature work out — he uses Jose Tabata as a particularly regrettable deal for the Pirates — but the cost certainty they provide is valuable. Brink notes that the Bucs will be on the hook for $42.25MM in 2017 — the last guaranteed year of the Andrew McCutchen and Francisco Liriano contracts — for the combined salaries of Harrison, McCutchen, Liriano and Starling Marte.

Torii Hunter told reporters prior to today’s home opener that the Royals, Mariners, Rangers and Orioles were all interested in him before he made the decision to sign with the Twins, tweets the St. Paul Pioneer Press’ Mike Berardino. The Royals, in particular, seemed to tantalize Hunter, per Berardino: “Those guys going to the World Series, that was very appealing,” Hunter added.

With rosters being finalized around the league, it’s a busy time for players departing and ascending to the 40-man roster. Here’s the latest:

The Twins announced that they’ve selected the contract of outfielder Shane Robinson, who had been in camp on a Minor League deal. The 30-year-old Robinson had previously spent his entire career in the Cardinals organization and will presumably serve as the right-handed half of a center field platoon with Jordan Schafer. Minnesota entered Spring Training hoping that Aaron Hicks would show progress and win the center field job outright, but he struggled throughout the month and was optioned to Triple-A, paving the way for Robinson to make the roster. In parts of five seasons with St. Louis, Robinson is a .231/.303/.308 hitter in 452 plate appearances. He’s received strong marks at all three outfield spots, per UZR and DRS, and he hit .283/.340/.370 in Grapefruit League action this year.

Earlier Updates

The Reds are set to add several veterans to their 40-man roster, as John Fay of the Cincinnati Enquirer tweets. Veteran righties Kevin Gregg and Jason Marquis will be joined by reserves Brennan Boesch and Chris Dominguez on the Opening Day roster, and all will need a 40-man spot. That crunch already led the team to outright reliever Sam LeCure, and several other slots will need to be created before things are official.

The Rockies have selected the contract of right-hander Rafael Betancourt, the team announced last night (on Twitter). Betancourt, who will turn 40 at the end of this month, has gone through a somewhat remarkable comeback, recovering from Tommy John surgery that he underwent as a 38-year-old to return to the 40-man roster. The former Rox closer has had an excellent spring, yielding just one run on eight hits and a walk with 10 strikeouts in 8 2/3 innings. He adds another arm with closing experience to what is looking like a fairly murky bullpen situation in Colorado. It’s worth mentioning that setup man Rex Brothers was optioned to Triple-A and won’t be a factor in the ’pen in the season’s early stages.

Cubs righty Jacob Turner will likely not return to action for another spring game, MLB.com’s Carrie Muskat reports, but medical review after he experienced elbow discomfort revealed no ligament damage. “I’m just going to see how it feels,” said Turner. “The plan is four to six weeks of not throwing, and then go off how I feel.” Given his lack of options, I would expect the club to bring him along quite slowly — possibly utilizing a 60-day DL stay to free a roster spot.

Meanwhile, here are some roster situations percolating elsewhere in the National League:

We noted earlier today that Tony Cingrani is destined for the Reds pen. John Fay of the Cincinnati Enquirer discusses the implications of that move for the team’s rotation battle. Another candidate — David Holmberg — was bumped down to minor league camp, leaving the relatively inexperienced Raisel Iglesias and Anthony DeSclafani to fight veteran non-roster invitees Jason Marquis and Paul Maholm for two permanent spots (and a temporary substitute for Homer Bailey to start the year). Skipper Bryan Price explained that considerations of control will come into play: “The thing is, we’ve got veteran guys like Marquis and Maholm and we don’t want to use them one start,” Price said. “If they’re going to be on our team, the hope is they’re on our team for the entire season if not longer. That’s how we have to look at it. You can back-and-forth a young guy. He can start a game or two, go down the minor leagues or go into the bullpen and help as a long guy. Marquis and Maholm are looking more like long-term, start-to-finish options for us.”

The Diamondbacks will be fascinating to watch this year, albeit not necessarily in terms of the on-field product, Ken Rosenthal of FOX Sports writes. As he notes, the team’s newly-installed front office leaders seem to have different ideas than many of their counterparts in the industry. While the organization is saddled with some less-than-ideal contracts, and seems higher on several players than others, it nevertheless has no shortage of young talent, trade chips, and roster options. That should make Arizona an active player in the transactional game over the course of the season.

Meanwhile, it is time for the Mets to press forward with delivering a winning team, even with Zack Wheeler likely lost to Tommy John surgery, Ken Davidoff of the New York Post writes. In the immediate term, there have been conflicting signals on how the club will fill in for Wheeler, with skipper Terry Collins saying Dillon Gee will move back to the rotation, GM Sandy Alderson declining to provide such a clear answer, and Joel Sherman of the New York Post reporting that prospect Rafael Montero could have a chance at breaking camp. In the aggregate, there is enough depth and talent to make up for losing Wheeler, says Davidoff, removing his injury as an excuse if a legitimate contender does not emerge. For his part, Sherman wonders whether the club has staked too much of its future on the health and development of young arms, though it seems worth echoing Davidoff’s point here: the sheer number and upside of the alternatives in camp give New York ample options.

The Reds announced that they’ve signed veteran right-hander Jason Marquis to a minor league deal with an invitation to big league Spring Training.

The 36-year-old Marquis, a client of ACES, spent much of the 2014 campaign recovering from Tommy John surgery and worked out in front of Reds scouts last May before ultimately signing a minor league deal with the Phillies. In 51 2/3 innings with the Phillies’ minor league affiliates, he posted a combined 4.1 ERA with a 43-to-13 K/BB ratio.

Marquis’ most recent Major League work came as a member of the Padres, with whom he spent parts of the 2012 and 2013 seasons. Signed by the Twins in 2012, Marquis hurled 34 dreadful innings with Minnesota (8.47 ERA) before latching on with the Friars and working to a 4.05 ERA in 211 1/3 innings from 2012-13. In total, the sinker specialist has worked to a 4.56 ERA with 5.3 K/9, 3.5 BB/9 and a 50.7 percent ground-ball rate in 1921 career innings between the Braves, Cardinals, Padres, Twins, Cubs, Nationals, D-Backs and Rockies. And, as far as pitchers go, he’s respectable with the bat, as evidenced by a .196/.214/.278 career batting line. (The league-average pitcher hit .122/.153/.153 in 2014.)

The Phillies announced that they have released veteran right-hander Jason Marquis from his minor league deal.

The 36-year-old Marquis signed with the Phillies back in early June as the longtime Major Leaguer was on the road back from Tommy John surgery. He made eight starts for the Phillies’ Triple-A affiliate at Lehigh Valley, pitching to a 4.63 ERA with 6.9 K/9 and 2.5 BB/9, totaling 46 2/3 innings. Marquis was slowed by a sore back and eventually placed on the minor league disabled list with an oblique injury, though he recovered and made a start as recently as Saturday.

It’s possible that a team in need of veteran pitching depth will take a look at Marquis for the season’s final month. In parts of 14 Major League seasons, Marquis has a 4.56 ERA with 5.3 K/9, 3.5 BB/9 and a strong 50.7 percent ground-ball rate.

The Phillies announced that they’ve signed right-hander Jason Marquis to a minor league deal. The 35-year-old veteran is a client of ACES.

Marquis underwent Tommy John surgery last July but said a few months later that he didn’t intend for that operation to be the end of his career. He’s been working out for teams of late, recently throwing his fastball between 88 and 90 mph in an audition for the Reds.

Marquis’ command took a step back in 2013 with the Padres, as he walked a career-worst 5.2 hitters per nine innings (some of those struggles may have been due to his elbow injury, of course). However, his ground-ball rate remained a strong 52.3 percent — his fifth consecutive season with a ground-ball percentage north of 52.

The sinkerballing Marquis is a veteran of 14 Major League seasons with the Braves, Cardinals, Cubs, Nationals, Rockies, Twins, Diamondbacks and Padres. In 1921 career innings at the big league level, Marquis owns a 4.56 ERA with 5.3 K/9, 3.5 BB/9 and a 50.7 percent ground-ball rate. He can serve as veteran rotation depth for the Phils when healthy, as the team has already seen injuries to both Cliff Lee and Cole Hamelsthis season in the Major League rotation (the latter is healthy now). Additionally, Cuban signee Miguel Gonzalez is also working his way back from injury and isn’t close to appearing in the Majors.

As expected, recently signed Red Sox shortstop Stephen Drew has cleared waivers and appeared in his first minor league game for the organization, reports Pete Abraham of the Boston Globe (via Twitter). The procedural move of placing Drew on revocable outright waivers — a mechanism through which claims are rarely made — was needed since he inked a big league deal. Here’s the latest from around the game:

The Brewers will call up top pitching prospect Jimmy Nelson to start Sunday to take the rotation turn of Yovani Gallardo, tweets Tom Haudricourt of the Milwaukee Journal Sentinel. At this point, at least, it seems that Nelson may only get one start, as Gallardo is not expected to miss significant time. As I explained back in April, Nelson already has 27 days of service to his credit. Accordingly, if he did stay in the bigs from this point forward, he would accrue enough service time to set himself up to become eligible for an additional year of arbitration as a Super Two player, though he will not be able to pass the one-year service mark by the end of the year.

Milwaukee’s decision to deal for reliever Will Smith (in exchange for outfielder Norichika Aoki) has been a key element in the team’s success this year, writes Ken Rosenthal of FOX Sports. The team’s pro scouting staff gave Smith high marks, leading GM Doug Melvin to pull the trigger on the trade. He has allowed just one earned run in 21 2/3 innings of work, posting 12.9 K/9 against 4.2 BB/9.

Pitcher Jason Marquis was scheduled to throw for scouts today, Rosenthal reports in the same piece. The 35-year-old had Tommy John surgery last summer after tossing 117 2/3 innings of 4.05 ball for the Padres.

Another former big leaguer looking to make a return is infielder Bill Hall, who tweets that he is on the comeback trail. The 34-year-old has spent time at third, short, second, and all over the outfield in his 11 seasons of MLB action, and owns a career .248/.308/.436 line. He spent last year with the Angels’ Triple-A affiliate, putting up a .225/.321/.407 mark with 17 home runs in 452 plate appearances.

Ben Badler of Baseball America has the latest updates on the July 2 market. Yesterday, Badler ticked through the top ten expected bonuses among players eligible to sign for the 2014-15 period, along with the clubs expected to land them. Leading the way is infielder Gilbert Lara, who has been linked to the Brewers and could earn $3MM. Four of the players are expected to go to the Yankees, with the Rays, Red Sox, and Blue Jays also said to be set up for some large outlays among AL East clubs. (The American League could also be in line to pick up the other two players on that list, with the Mariners potentially in position to sign outfielder Brayan Hernandez and the White Sox predicted to land righty Huascar Ynoa.)And today, he profiles a set of field position prospects who figure to be among the best available players, headlined by Venezuelan shortstop Kenny Hernandez, who Badler says could get a nine-figure bonus.

Meanwhile, the Yankees are reportedly prepared to ink Korean shortstop Hyo-Jun Park for a $1.1MM bonus, according to a report from Korean outlet Naver (Korean language link; translated article; hat tip to River Ave. Blues ). Jason Cohen of Pinstripe Alley recently compiled the available information on Park, who is said to be a solid all-around player.
